An electron was ejected from the surface of cesium metal with a speed of 6.74*10^5 m/s.Given that the threshold energy for the removal of an electron from the cesium metal is 2.90*10^-19J. Calculate the incident wavelength in nanometers. For this problem, I believe we use the KE=E photon-Eo. However, I am having trouble getting from the formula to the desired answer of 400 nm.
Given this quantum state: ¥(r,0,0) = R(r)(√₂Y+Y¹-Y₂²), a) measured: |Z|² , find possible outcomes, corresponding probabilities and the average value b) repeat the same but instead with measured say Lz c) If you had first measured Lz to be planck's constant, and then measured |Z|² what can be said about the result of |Z|² ?
Planck’s constant has the value h = 6.626 × 10–34 joule-seconds (J-s), and the speed of light is c = 3 × 108 m/s. Using these values, calculate the wavelength carried by photons emitted with an energy of 1.1 × 10-19 J.
In kinetic theory of gases, atoms are modeled as point masses m with mean speed v related to temperature T by m v^2 = 3 k T, where k is Boltzmann’s constant. Assuming gas atoms travel several thousand Angstroms between collisions with each other, how cool would hydrogen gas need to be before quantum mechanics would have to be taken into consideration?
